Ex 12.1, 3 See the figure and find the ratio of (a) Number of triangles to the number of circles inside the rectangle. Number of triangles = 3
Number of circles = 2
∴ Ratio = (𝑁𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑡𝑟𝑖𝑎𝑛𝑔𝑙𝑒𝑠)/(𝑁𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑐𝑖𝑟𝑐𝑙𝑒𝑠)
= 3/2
∴ Ratio is 3 : 2
Ex 12.1, 3 See the figure and find the ratio of (b) Number of squares to all the figures inside the rectangle.Number of squares = 2
Number of figures inside rectangle = 7
∴ Ratio = (𝑁𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑠𝑞𝑢𝑎𝑟𝑒𝑠)/(𝑁𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑓𝑖𝑔𝑢𝑟𝑒𝑠)
= 2/7
∴ Ratio is 2 : 7
Ex 12.1, 3 See the figure and find the ratio of (c) Number of circles to all the figures inside the rectangle.Number of circles = 2
Number of figures = 7
∴ Ratio = (𝑁𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑐𝑖𝑟𝑐𝑙𝑒)/(𝑁𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑓𝑖𝑔𝑢𝑟𝑒𝑠)
= 2/7
∴ Ratio is 2 : 7
